“Nothing outside my reasoned choice can hinder or harm it – my reasoned choice alone can do this to itself. If we could lean this way whenever we fail, and would blame only ourselves and remember that nothing but opinion is the cause of a troubled mind and uneasiness, then by God, I swear we would be making progress.” Epictetus, Discourses.
Opinion. Everybody has one. To what extent does yours cause you to worry and doubt yourself?
Don’t beat yourself up. Share your worries with another person and listen to their opinion. You’ll not see the world exactly the same way as them. Then you’ll realise that the way you see things is up to you. Your choice.
